Nickel is the metal that made the jet age possible, not to mention margarine and bicycle sprockets. In the latest installment in his journey through the periodic table, Justin Rowlatt travels to Rolls Royce to discover the incredible materials science that this chemical element and its super-alloys have driven, as well as the miniscule market for another, far more valuable metal - rhenium.

Justin also descends deep into the bowels of University College London with Professor Andrea Sella to encounter the clang of a Monel rod, a magic trick with a Nitinol paper clip, and an almost uncuttable piece of Inconel.
